The use of non-standard screws If the nut of a product needs to be installed outside, and the space inside it is too narrow to allow the press head of the riveter to enter the pressure riveting and the budding method, etc., the strength requirements cannot be achieved. Rivets are not feasible. Must use riveting. Applicable to all thickness plate, pipe (0.5MM-6MM) fastening field. The use of pneumatic or manual riveting gun can be riveted once, convenient and firm; replace the traditional welding nut, make up for the thin metal plate, thin tube welding is easy to melt, weld nut is not smooth and other shortcomings.The comparative test samples were all ceramic sheet sealed kitchen faucets, involving 50 samples produced by 50 companies in eight provinces and cities including Beijing, Shanghai, Guangdong, Fujian, Zhejiang, Jiangsu, Jiangxi and Hebei. By entrusting the National Building Materials Industry Construction Hardware Plumbing Product Quality Supervision, Inspection and Testing Center to test the faucet's logo packaging, salt spray test, flow, sealing performance, water efficiency, and lead concentration, there are 17 faucet samples in 50 samples. The project failed to meet the standard requirements, accounting for 34%.Electronic Products CNC Lathe Partswebsite:http://www.pin-good.com/lathe-parts/electronic-products-cnc-lathe-parts/
